Marianne S. DeSoto

Marianne S. DeSoto serves as a Contract Specialist responsible for managing the full lifecycle of federal acquisitions, from requirements definition and market research through solicitation, evaluation, award, and contract administration. She plays a critical role in ensuring compliance with federal procurement regulations while advancing agency mission objectives through efficient and transparent contracting practices. Her portfolio primarily encompasses transportation, facilities support, and professional services contracts, with a focus on complex, multi-year procurements requiring detailed technical specifications and performance-based outcomes. She works closely with program managers and acquisition teams to align contracting strategies with operational needs. While specific contractor names are not available, Marianne cultivates relationships with a diverse range of vendors, including large prime contractors and small businesses capable of delivering specialized transit, ambulance, and equipment supply services. Her contracting patterns reflect a preference for competitive, open solicitations, with a strong emphasis on fair and reasonable pricing, past performance evaluation, and clear statement of work development. She frequently engages with vendors possessing relevant industry certifications and proven delivery capabilities in regulated service environments. Marianne demonstrates a measured commitment to small business participation, with approximately 10% of her awards directed toward 8(a) competed contracts, reflecting a strategic but not dominant emphasis on socioeconomic programs. The majority of her acquisitions—90%—are conducted without set-asides, indicating a preference for full and open competition unless specific statutory or policy requirements dictate otherwise. Her approach balances compliance with socioeconomic goals while maintaining competitive integrity and value for the government. Her primary procurement focus lies in NAICS 485999 (All Other Transit and Ground Passenger Transportation) and 423490 (Other Professional Equipment and Supplies Merchant Wholesalers), with additional activity in facilities support services, ambulance services, and information services (NAICS 511210). She specializes in procuring specialized vehicles, medical transport equipment, maintenance services, and mission-critical supplies, demonstrating deep familiarity with operational requirements in public safety and transportation infrastructure sectors.
